.dkpplicatibn filed January lVIy invention is a. vending machine, adapted to vend sheetsotpa per and in particular paper for covering toilet seats.

An object of myinventionis the provision of-a vending machine operatedby a crank, in. which the insertion of .a coin causes the crank to operatea. drum, the

drumunwindinga paper gtrom a reel orroll and dispensing one sheet for each revolu tion otthe crank.

A further. object of myginvention is to caus a n rt e n were el m in tr-a f r a iving f rce o h rank o the drum 1 and areciprocatihg device; adapted or ieet he: c 1 ,.-fr t in lo n t take the plaee of the coin in transmitting the driving force from the, crank to the A turtlrerpbject bi my; invention is t;

tor-m a drum with a projection on its surface adapted to fit' a cutout section of the paper and to feed. same. I u

In; the construction of my invention I mount" a drum in a cabinet structure, preterably above-a reel or roll of paper, the paper having cut-out portions and preferably hav ing side notches; and, perforations to allow severanceinto sections. The drum has a projection on the surface adaptedto fit in the cut-out portion, of the paper and thereby positively feed the paper. A ratchet having-a single tooth is mounted on the ends of the drum shaft and a weightedlever having a pawl tooth is pivotally mounted is formed in a hollow radial arm designated theejector arm, keyed or otherwise secured to the crankshaft. Anejector is mounted in this. arm spring pressed into itsinnermost position. When acoinis inserted in the coiin chuteand rests. against the upper end of the ejector-in the ejector. arm, and on turn-ing the crank, the p'i'rojection on the arm. engages; the coin and transmits motion to the ejector. arm and thereby turns the s te e t e. drum ,Aeta imary sc m opeatesoti ejeet'erin .eieetor armfind f 19', 1926.; Serial nowaieo.

The reel or roll 15 shown particularly in Figs. 3, 4 and is journaled in open topped bearings 16 and has the paper 17 wound thereon in the form of an ordinary roll.

The "ending drum designated generally.

' by the numeral 18 is shown particularly in gage the paper at either the perforations as hereunder mentioned or to form perforations which allow easy tearing.

" The means .for controlling the vending of' the paper is substantially as follows, being shown particularlyin Figs. 4, 5 and 9:

An idler 25v is ournaled in the cabinet in any suitable manner, the web 26 of the paper passing thereover. Pressure rolls 27 mounted on arms .28up'ivotally mounted on a cross bar 29 are normally pressed against the vending'drum by means of springs 30.

Circular ratchets31 and 32 are attached to the front andrear ends of the cabinet surrounding the shaft and each has a single notch 33. These notches engage apawl tooth 34 of the weighted arms 35 carrying a'transverse weight 36 at their outer end, the arms being pivotally mounted on the rod 29 or otherwise suitably supported. The delivery slot 7 has an apron 37 onw'hich the weight 136 rests, holdingrtheend of the web on the apron inside of the: cabinet. as indicated in Fig. 5 after a sheet of paper has been torn therefrom. j

:The operation of the vending drum is sub stanti ally as follows:

WVhen the shaft is turned on account of the projection 23 fitting in the. cut-out por- .tion 38, of the sheet 39, forming part of the l web 26 as shown in Fi-g. 10, the paper is fed ready tearing of the paper.

out of the delivery slot, the rotation of the drum being in the direction of the arrow 40 of Fig." 5. The web of paper is preferably formed with a series of perforations 41 and notches 42, the prongs 24 engaging the paper at the perforations or if unperforated paper is used these prongs will formcuts allowing As the paper is forced out of the delivery slot it maybe forations.

grasped by the purchaser and when the drum has come to rest as hereunder mentioned, the sheet of paper may be torn at the per- The coin controlling mechanism is substantially as described, being illustrated particularly in Figs. 4, 6, 7 and 8. The crank wise secured to the shaft 12, having a lo tating seat with the journal 22 as indicated by the numeral 49;- these features being shown in detail in Fig. 8.

A radial hollow ejector arm 50 extends outwardly from the block 48 and atits outer end has a coin slot 51. A transverse opening or slot 52 extends through'the ejector arm and forms an opening across the'coin-slot. An ejector 53 is mounted in the hollow space 54 of the ejector arm and has a base 55 adapted to rest on the block 48. An offset abutment 56 extends laterally from the ejector. This ejector hasa stem section 57 adapted to fit in the coin slot and to slide therein. A compression spring 58 is positioned' between the abutment V 56 and the outer end 59' of the ejector arm and nor mally holds the ejector inwardly. r

A cam 60 is attached to the outer end 2 of the cabinet, this cam being spiraled, hav-- -ing its inner end 61 close in to theblock 48 as indicated in Figs. 7 and-8 and its outer end 62 situated a sufiicient distance so that i when the ejector arm rotates the stem section 57 of the ejector is forced outwardly in the coin slot across the transverse slot 52.

Inorder to hold the'crank in its upper position when stationary, a spring'pressed ball and socket device 63 co-acting'between the crank and the wall 46 is secured thereto, the socket being positioned to engage the ball and hold the crank in the desired upright position. i V

The operation of my coin controlled mechanism issubstantially as follows:

\Vhen the crank is in the uppermostposr tion or hanging downwardly, or in any other position except when the projection 47 is directly'in the coin slot, a coin may be inserted'therein and rests on the upper end of the stem portion of the ejector. When the handle is turned in the proper direction, the

projection 47 engages the coin and thus turns 5 the hollow ejector arm in the direction of the arrow 64 of Fig. 7, by transmitting the presure to the arm, thence to the block 48 which is keyed to the shaft 12. This action rotates the shaft and hence the drum, the

drum functioning as above described.

In this action the abutment 56 rides on the outside surface of the cam'60 and gradually thrusts the coin outwardly of the coin chute until the ejector arm is in the reverse position, that is, extending downwardly when thecoin is completely ejected. At this state of the movement the stem section 57 of the ejector takes the place of thecoin across the transverse slot 52 andas the projection 47 bears thereagainst the ejector arm and the mechanism to which it is connected rotates to the uppermost position. When the abutment is free of the cam at the upper end 62 the spring 58 immediately thrusts the ejector downwardly, thus preventing any" articles or lengths of paper andthat the coin controlled mechanism may also. be considerably changed to suit different types of mechanism operated thereby. Such changes in the general construction and specific details will be within the spirit of my invention as set forth in the description, drawings and claims.

Having described my invention, what I claim is:

l. A vending machine comprising in combination a drum, means to support sheet material to be vended by the drum, means on the drum to engage sheet material, a rotatable shaft forming a mounting for the drum, a coin controlled mechanism mounted on the shaft a crank loosely rotatable on the shaft, the crank having a projection rigidly connected therewith, the projection being adapted to engage a coin in the coin.
